SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 699,943, dated May 13,1902.

Application filed March 23,:'1901-A Serial No. 52,526. (No model.)

'T0 all whom, tm/tty concern: 'I y Beit known that I, CHARLES A.BRINLEY,0E Y the city and county of Philadelphia and StateofPennsylvania,'have invented an Improve! ment in Shaft-Hangers, of whichthe follo'wf. ing is a specification. l My invention has reference toshafthang` ers; and it consists of certain improvements all of which arefully set forth in the follow-n lowing specification and yshown in theaccom'- panying drawings,which form a part thereof. The object of myinvention is to provide a suitable construction of drop-hangerforshafting, which,while retainingthegeneral characteristicshape ofv'suchhangers found by eX- perienceas best adapted for the purpose,shall Aembody special improvements whereby commercial sections of rolledironor steel may be employed in its' construction. Theresult. 'of suchconstruction is-to produce ahanger Aof composite formand of 'greatrigidity cou`- ,pled with lightness,thelatter features being secured byproperly shapingand bracing thfe light rolled-metal barsusedinv theconstrue-i tion.

My object is further toV soconstruct the hanger that the lower orbox-supporting portion may be detachable and employedin com-1 hinationwith hanger-bases havingthe arms of various lengths to secure differentdrops, thereby simplifying the manufacture to suit yall possibledemands, and to provide means whereby the lower parts carrying the boxcan be made up without reference tothe drop and any one ofthe lowerparts canbe employed with any upper part -of several; such upper parts,thus simplifying the manufacture.

In carrying out my invention I form the base and depending arms of theyhanger ofrr lighter rolled iron or steel, preferably: of LL shape i incross-section, and I so'shape and combine the several parts that theproper c onfiguration isfsecured'with a simple bracing, Ll which permitslightness to be had withoutimpairing the f great -`stability and rigidity`v sonecessary to shaft-hangers in commercial use. The lower endslof the depending arms or body :portion of the hanger-frame are unitedVby suitable bracing, adapted also to carrythe In place of making thelower portion of the hanger-frame arms or members integral with the:upper or base portion it may be made separate and riveted, bolted, orotherwise secured to the upper portion, as will be more fully explainedhereinafter. The lower p01'- 4tion of the hanger may have the lowercrossbraces'riveted or otherwise secured to the upright members; but Iprefer to have the lower transverse brace detachably secured in place,so 'that the shaft and journal-boxinay be put into place Within thehanger from below and the brace and support for the box then secured inplace by preferably detachable means,such asboltsf My invention will bebetter understood by reference to the drawings, in `which-- Figure 1 isa fronte elevation of a shafthanger embodying fmy invention. Fig. 2 isan inverted plan view ofsame. Fig. 3 is a 'side elevation of same;IiFig. 14 is a front ele- 'vation of a modiicationof same, showing therdetachable lower portionV carrying Yfthe journal-box; and Fig. 5 isl aAplan view of the hanger shown in Fig. 4.

A represents four depending arms of angleiron, their upper ends beingbent outward, as at A', and their lower ends bent vertically, as

atffD.' The middle portions of these arms A vare oblique and also,preferably, spreading at their upper ends to give greater base ofsupport. To make a sharp bend between parts A andfA, one rib of theangle-iron is notched out and the edges butted and the jointstrengthened by corner-braces B. The outer pairs by the cross-plates C,riveted to them, sai'dfplates having the necessary holes c for attachingthe hanger to the ceiling-timbers. These plates C are preferably ofangle-iron,

vends of the footpieces A are connected in transverselyarranged,and inaddition to these `thefangleiron arms A may be connected in pairsin' theother direction atthetop by bars lVB of any suitable cross-section,whichare properly riveted in place, as shownv In thismanner the parts A, C,andlB makea strong and extensive base of support, andv thereby. pre-Vent any tendency to rocking due to strains upon the shafting.

The lower ends D of the arms A are preferably vertical, and henceparallel. They are lconnected in pairs by the braces H H, the two pairsof arms thus formed being also connect- IOC ed by braces E F. Thesebraces E F are arranged at different elevations, so as to leave a spacebetween them sufficient for the journal-box J, through which the shaft Gpasses. The other braces H H are at a middle elevation or between thelevels of the two braces E F. As will be seen from Fig. 2, the brace Eis composed of two U-shaped pieces riveted together to form an H-shapedstructure, the ends of the arms being bolted to the flanges of the partsD of the lower body portion. The brace E is detachably secured to thesaid parts D by bolts K, whereby it may be removed for inserting theline or" shafting and then secured in place to support it. The adjustingand supporting screw e passes through the bar formed in this brace. Theupper brace F is made in exactly the same way and is provided with asimilar screw f for holding the box.

`The sorewf presses down upon the cap of the box, and the screw epresses upward under the bodyof the box, so that theirjoint action holdsthe two parts of the journal-box together, as well as adjusts itsposition in the hanger. The side braces H H are made like I-shapedstruc- 'tures formed ot' two pieces riveted together and with theflanges riveted to the flanges of parts D, as shown in Fig. 3. Screws hpass through these braces H and act as adjusting and steadying devicesfor each side of the journal-box G. The braces F and H may be riveted tothe parts D, as shown, or permanently attached in any suitable manner.'lhe braces H, E, and F thoroughly connect and brace the ends D of thearms A, so as to inipart great rigidity, and form excellent supports forthe screws, which directlyT sustain the journal-box.

The foregoing description more specifically relates to Figs. l, 2, and3, in which the parts A and D are in one integral structure. I will nowrefer to Figs. 4 and 5, which show a modified form of base and asectional construction for the hanger-frame. In these figures the arms Aare made flaring, as before, but are riveted direct to the flanges of anangle-iron base B2. In this case the angle-irons B2 B2 are curved, asshown, and riveted together at the middle atb and constitute an Xstructure, the free arms of which are riveted to the upper ends of thearms A. The cross-plates C are used also in this case as in the otherand may be of flat metal or rolled shapes, as preferred.

The lower ends of the arms A are preferably made similar to those ofFig. l, but shorter and without bracing. The journal-box-supportingdevices,preciselylike those described, (except that the parts D areindependent of the arms A, as shown in Fig. 4,) are then placed inposition, so that the arms A overlap the parts D', and are riveted orbolted together at d. In this manner the lower body portion or journal-box-supporting structures may be made up in quantities and theupper portions of the hanger made to snit the special requirements as todrop or construction of base.

The lower body portion when made separate is the same for a number ofdifferent upper body portions or bases, and if these parts are kept instock hangers of any desired drop or shape of base may be made by mereassembling of the upper and lower body portions by uniting the uprightmembers of the two parts. Of course in cases Where a large order isdesired of a hanger of one drop the upright members may be madecontinuous orintegral, as in Fig. l.

A hanger oi' this construction is cheap to make, is lighter, andconsequently cheaper to transport, and is stronger than cast ironhangers commonly employed.

Vhile I have shown my improved hanger as made largely from angle-iron, Ido not confine myself to any special cross-section of rolled metal, andwhile I prefer the construction shown as being an excellent embodimentof my invention I do v,not confine myself to Ythe minor details, asthese may be modified without departing from the spirit of theinvention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
